I am entering new ground beyond myself and my friend’s experience. I have recently completed a motor rebuild with oversized CTR pistons and Jun III's managed by an Apexi Power FC. It's clear the current stock injectors are not going to cut it. I would like to replace them with either 375 or 440 cc RC injectors. Would either of these supply either to much or to little fuel? What type of injectors are you all using with a similar setup to this one?

 

I am running RC 440cc injectors, with TODA B's and CTR pistons and PowerFC, working fine so far (still running in), you should be able to go with 440s no problem with the PowerFC

 

310-370 is fine
